[ncl-talk] Coherence analysis

[Dennis Shea]

For sure, these were created with NCL. However, I am not sure how these
were created.

NCL's *specxy_anal*
<http://www.ncl.ucar.edu/Document/Functions/Built-in/specxy_anal.shtml>

could have been applied *at each longitude* (loop over longitudes) and the
results stored in arrays:

   COHER(frq,lon), PHASE(frq,lon), COSPC(frq,lon),  QUSPC(frq,lon)

Good luck
